Can someone help me?
Hey @carlos_eduardo
The problem is that your Postgres instance is running on your system localhost which is not accessible from public internet. The connection string requires a host that’s accessible.
One technique that is usually used to expose localhost services is called tunnelling. You can explore that and use services such as Localtunnel ~ Expose yourself to the world or https://ngrok.com/ to make your local Postgres instance accessible during development.
Note that this is only for development purposes, ideally you should be using a Postgres instance hosted somewhere online.
